The U- prises an arcuate section I3 of the same conshaped members I9 and 2@ are joined together figuration as the arcuate section I, but opposed by a series of spot Welds 23 and the fabricated thereto. Section I3 has at its edges flanges I4 end pieces I8 are attached to the stud by filling and I5 which are parallel to iianges II and I2. the ends of the casing with a nailable cementi- 55 tious mix, either of the same or a dilerent nature than that described above, telescoping the ilanges 2| and 22 of member I9 over the ends of the stud, and then driving nails 25 and 26 through the legs 2l and 22 of the U-shaped member IS into the mix within the interior of the stud, and laying the stud with the end piece so attached aside for the mix to dry. The end pieces are optional. If desired they may be attached when the stud is used. Any stud may be .shortened on a job and an end piece attached after such shortening.

A stud of the structure described and illustrated has great strength. The two arcuate side members lo and I3 are joined together in a manner which prevents relative movement therebetween. They will strongly resist torsional or twisting end-to-end strain which may be applied thereto. They will not buckle, even under great Weight. They will not bend between ends under wind or other pressure applied between the ends. The cost of production or fabrication is slight because of the limited amount of spot Welding required. It is also possible to fabricate such a stud by continuous movement through a spot welding machine, such machine welding the stud at opposite sides at spaced intervals, the stud frame being advanced intermittently predetermined distances. The cementitious fill may be conveniently inserted after the fabrication of the casing is complete. The ll and attachment of the end pieces may be made at an extremely low cost.

The core is of sucient width and depth to receive nails in the usual manner. It completely iills the interior of the stud and resists lateral compression of the casing. The double thickness of the stud at the nailing edges increases the shearing resistance to the retraction of any nail once inserted thereinto. The core prevents any tendency of the casing to bend inwardly (which is the natural way for the metal parts I0 and i3 to deform) and increases the strength of the stud to withstand the usual compression stresses to which a stud is subjected.

I claim:

1. A stud comprising paired opposed arcuate members of nail-penetrable material having terminal tangential flanges, and a nailable cemen-e titious core enclosed by said members and their flanges, the anges of said members being associated in reverse overlapped relation.

2. A stud comprising paired opposed arcuate members of nail-penetrable material having anges at their edges, the flanges of one member alternately overlying and underlying the corresponding iianges of the other member, and a nailable cementitious core enclosed by said members and their ilanges.

3. A stud comprising a nail-penetrable metal casing and a nailable cementitious core, the metal casing comprising a pair of correspondingly shaped members having arcuate side walls of a single lamination of metal, and top and bottom walls of two laminations of metal.

4. A stud comprising a nail-penetrable metal casing and ai nailable cementitious core, the metal casing being composed of a pair of counterpart, opposed, arcuate members having parallel superposed flanges, complemental anges of the members being joined by spot Welding and providing nailing faces of double thicknesses of metal and the inner and outer faces of the flanges of one member contacting the cuter and inner faces of the flanges of the other member.

5. A stud comprising a nail-penetrable metal casing and a nailable cementitious core, the metal casing being composed of a pair of counterpart opposed members having parallel superposed flanges, complementary flanges of the members alternately overlying and underlying their companion flanges upon two faces of the stud and providing nailing faces of a double thickness of metal, and the inner and outer faces of the flanges of one member contacting the outer and inner faces of the flanges of the other member.
